1 This sorting machine for load used pneumatic loading, mainly used for compression spring preloading and testing.
2 Test mode : load at a determined height.
3 It is mainly used in spring factories, power machinery factories and other units. Because of the fast testing speed of the spring sorting pressure testing machine, it is especially suitable for mass testing in workshops.
Features and functions
1 There are two working positions on the rack. The piston rod of the cylinder drives the upper pressure plate up and down, and the lower pressure plate and sensor are installed on the support.
2 Adjust the rising position switch on the cylinder according to the spring height, which can reduce the return trip and improve the efficiency during batch test.
3 Test operated by foot valve.
4 The test results are indicated by the screen display and indicator light, and the corresponding indicator light is on in five colors according to the set qualified area when using, so as to facilitate the sorting spring without look!
5 Emergency stop function :In case of emergency, please press the emergency stop switch and the cylinder stops moving.
